2日 1982年发射的西联星-4通信卫星停止工作,卫星设计寿命7年,实际工作了10年。 4日美国休斯飞机公司最近同阿尔法·利罗康姆公司签订了制造3颗通信卫星的合同,总金额达3亿美元左右。这3颗卫星将主要用于电话、电视、数据传输以及电话会议等。第一颗卫星计划在1994年5月发射,它主要为太平洋地区服务,其余两颗将在1994年晚些时候发射,分别为大西洋和印度洋地区服务。 8日美国太平洋时间23时07分,美空军从加利福尼亚州的范登堡空军基地发射场用“大力神4”型运载火箭发射了一颗秘密军事卫星。据推测,这可能是颗“长曲棍球”式雷达成象侦察卫星。这是“大力神4”
On the 2nd, the Western Union Star-4 communications satellite launched in 1982 stopped working. The satellite has a design life of seven years and has actually worked for 10 years. On the 4th, the U.S. Hughes Aircraft Company recently signed a contract with Alfa Leroux to manufacture three communications satellites in a total amount of about 300 million U.S. dollars. The three satellites will be used mainly for telephony, television, data transmission and teleconferencing. The first satellite, scheduled to be launched in May 1994, will serve mainly the Pacific region and the remaining two will be launched later in 1994 and serve the Atlantic and Indian Ocean regions respectively. On the 8 th Pacific Time, at 07:07 U.S.A, the U.S. Air Force fired a stealthy military satellite from the launch site of the “Hercules IV” from Vandenberg Air Force Base launch site in California. Presumably, this may be a “lacrosse” radar imaging reconnaissance satellite. This is “Hercules 4”
